For what it is worth Me thinks any brand of bore guide that is gun and Cal. Specific far out shine the universal bore guides as they keep the cleaning rod in line with the bore so there is less chance of damage to the rifling and keeps the solvents out of the action.
I have 5 Possum Holler ones and they work fine as far as I can tell.
The two universal ones I have are not for spit, and they are top of the line.
